{3} And because ye are sons, God hath {f} sent forth the {g} Spirit of his Son into your hearts, crying, Abba, Father.

(3) He shows that we are free and set at liberty in such a way that in the meantime we must be governed by the Spirit of Christ, who while reigning in our hearts, may teach us the true service of the Father. But this is not to serve, but rather to enjoy true liberty, as it is fitting for sons and heirs.

(f) By that which follows he gathers that which went before: for if we have his Spirit, we are his sons, and if we are his sons, then we are free.

(g) The Holy Spirit, who is both of the Father, and of the Son. But there is a special reason why he is called the Spirit of the Son, that is, because the Holy Spirit seals up our adoption in Christ, and gives us a full assurance of it.

People's New Testament

4:6 Because ye are sons, God hath sent forth the Spirit. The spirit is bestowed not to make us sons, but because we have become sons by the faith. See Joh 1:12.

Crying, Abba, Father. See PNT Ro 8:15. Abba is simply the Syriac for father. It is found also in Mr 14:36 Ro 8:15. This spirit of adoption helps the son to realize that he is a son, and to look up to God and to address him, if a Semitic, as Abba; if a Greek as Pater; is an Anglo-Saxon, as Father.

Wesley's Notes

4:6 And because ye - Gentiles who believe, are also thus made his adult sons, God hath sent forth the Spirit of his Son into your hearts likewise, crying, Abba, Father - Enabling you to call upon God both with the confidence, and the tempers, of dutiful children. The Hebrew and Greek word are joined together, to express the joint cry of the Jews and gentiles.

Jamieson-Fausset-Brown Bible Commentary

6. because ye are sons-The gift of the Spirit of prayer is the consequence of our adoption. The Gentile Galatians might think, as the Jews were under the law before their adoption, that so they, too, must first be under the law. Paul, by anticipation, meets this objection by saying, Ye are sons, therefore ye need not be as children (Ga 4:1) under the tutorship of the law, as being already in the free state of "sons" of God by faith in Christ (Ga 3:26), no longer in your nonage (as "children," Ga 4:1). The Spirit of God's only Begotten Son in your hearts, sent from, and leading you to cry to, the Father, attests your sonship by adoption: for the Spirit is the "earnest of your inheritance" (Ro 8:15, 16; Eph 1:13). "It is because ye are sons that God sent forth" (the Greek requires this translation, not "hath sent forth") into OUR (so the oldest manuscripts read for "your," in English Version) hearts the Spirit of His son, crying, "Abba, Father" (Joh 1:12). As in Ga 4:5 he changed from "them," the third person, to "we," the first person, so here he changes from "ye," the second person, to "our," the first person: this he does to identify their case as Gentiles, with his own and that of his believing fellow countrymen, as Jews. In another point of view, though not the immediate one intended by the context, this verse expresses, "Because ye are sons (already in God's electing purpose of love), God sent forth the Spirit of His Son into your hearts," &c.: God thus, by sending His Spirit in due time, actually conferring that sonship which He already regarded as a present reality ("are") because of His purpose, even before it was actually fulfilled. So Heb 2:13, where "the children" are spoken of as existing in His purpose, before their actual existence.

the Spirit of his Son-By faith ye are one with the Son, so that what is His is yours; His Sonship ensures your sonship; His Spirit ensures for you a share in the same. "If any man have not the Spirit of Christ, he is none of His" (Ro 8:9). Moreover, as the Spirit of God proceeds from God the Father, so the Spirit of the Son proceeds from the Son: so that the Holy Ghost, as the Creed says, "proceedeth from the Father and the Son." The Father was not begotten: the Son is begotten of the Father; the Holy Ghost proceeding from the Father and the Son.

crying-Here the Spirit is regarded as the agent in praying, and the believer as His organ. In Ro 8:15, "The Spirit of adoption" is said to be that whereby WE cry, "Abba, Father"; but in Ro 8:26, "The Spirit itself maketh intercession for us with groanings which cannot be uttered." The believers' prayer is His prayer: hence arises its acceptability with God.

Abba, Father-The Hebrew says, "Abba" (a Hebrew term), the Greek, "Father" ("Pater," a Greek term in the original), both united together in one Sonship and one cry of faith, "Abba, Father." So "Even so ('Nai,' Greek) Amen (Hebrew)," both meaning the same (Re 1:7). Christ's own former cry is the believers' cry, "Abba, Father" (Mr 14:36).

Matthew Henry's Concise Commentary

4:1-7 The apostle deals plainly with those who urged the law of Moses together with the gospel of Christ, and endeavoured to bring believers under its bondage. They could not fully understand the meaning of the law as given by Moses. And as that was a dispensation of darkness, so of bondage; they were tied to many burdensome rites and observances, by which they were taught and kept subject like a child under tutors and governors. We learn the happier state of Christians under the gospel dispensation. From these verses see the wonders of Divine love and mercy; particularly of God the Father, in sending his Son into the world to redeem and save us; of the Son of God, in submitting so low, and suffering so much for us; and of the Holy Spirit, in condescending to dwell in the hearts of believers, for such gracious purposes. Also, the advantages Christians enjoy under the gospel. Although by nature children of wrath and disobedience, they become by grace children of love, and partake of the nature of the children of God; for he will have all his children resemble him. Among men the eldest son is heir; but all God's children shall have the inheritance of eldest sons. May the temper and conduct of sons ever show our adoption; and may the Holy Spirit witness with our spirits that we are children and heirs of God.

Matthew Henry's Whole Bible Commentary

Chapter 4

The apostle, in this chapter, is still carrying on the same general design as in the former-to recover these Christians from the impressions made upon them by the judaizing teachers, and to represent their weakness and folly in suffering themselves to be drawn away from the gospel doctrine of justification, and to be deprived of their freedom from the bondage of the law of Moses. For this purpose he makes use of various considerations; such as, I. The great excellence of the gospel state above the legal (v. 1-7). II. The happy change that was made in them at their conversion (v. 8-11). III. The affection they had had for him and his ministry (v. 12-16). IV. The character of the false teachers by whom they had been perverted (v. 17, 18). V. The very tender affection he had for them (v. 19, 20). VI. The history of Isaac and Ishmael, by a comparison taken from which he illustrates the difference between such as rested in Christ and such as trusted in the law. And in all these, as he uses great plainness and faithfulness with them, so he expresses the tenderest concern for them.

Verses 1-7

In this chapter the apostle deals plainly with those who hearkened to the judaizing teachers, who cried up the law of Moses in competition with the gospel of Christ, and endeavored to bring them under the bondage of it. To convince them of their folly, and to rectify their mistake herein, in these verses he prosecutes the comparison of a child under age, which he had touched upon in the foregoing chapter, and thence shows what great advantages we have now, under the gospel, above what they had under the law. And here.

I. He acquaints us with the state of the Old-Testament church: it was like a child under age, and it was used accordingly, being kept in a state of darkness and bondage, in comparison of the greater light and liberty which we enjoy under the gospel. That was indeed a dispensation of grace, and yet it was comparatively a dispensation of darkness; for as the heir, in his minority, is under tutors and governors till the time appointed of his father, by whom he is educated and instructed in those things which at present he knows little of the meaning of, though afterwards they are likely to be of great use to him; so it was with the Old-Testament church-the Mosaic economy, which they were under, was what they could not fully understand the meaning of; for, as the apostle says (2 Co. 3:13), They could not stedfastly look to the end of that which is abolished. But to the church, when grown up to maturity, in gospel days, it becomes of great use. And as that was a dispensation of darkness, so of bondage too; for they were in bondage under the elements of the world, being tied to a great number of burdensome rites and observances, by which, as by a kind of first rudiments, they were taught and instructed, and whereby they were kept in a state of subjection, like a child under tutors and governors. The church then lay more under the character of a servant, being obliged to do every thing according to the command of God, without being fully acquainted with the reason of it; but the service under the gospel appears to be more reasonable than that was. The time appointed of the Father having come, when the church was to arrive at its full age, the darkness and bondage under which it before lay are removed, and we are under a dispensation of greater light and liberty.

II. He acquaints us with the much happier state of Christians under the gospel-dispensation, v. 4-7. When the fulness of time had come, the time appointed of the Father, when he would put an end to the legal dispensation, and set up another and a better in the room of it, he sent forth his Son, etc. The person who was employed to introduce this new dispensation was no other than the Son of God himself, the only-begotten of the Father, who, as he had been prophesied of and promised from the foundation of the world, so in due time he was manifested for this purpose. He, in pursuance of the great design he had undertaken, submitted to be made of a woman-there is his incarnation; and to be made under the law-there is his subjection. He who was truly God for our sakes became man; and he who was Lord of all consented to come into a state of subjection and to take upon him the form of a servant; and one great end of all this was to redeem those that were under the law-to save us from that intolerable yoke and to appoint gospel ordinances more rational and easy. He had indeed something more and greater in his view, in coming into the world, than merely to deliver us from the bondage of the ceremonial law; for he came in our nature, and consented to suffer and die for us, that hereby he might redeem us from the wrath of God, and from the curse of the moral law, which, as sinners, we all lay under. But that was one end of it, and a mercy reserved to be bestowed at the time of his manifestation; then the more servile state of the church was to come to a period, and a better to succeed in the place of it; for he was sent to redeem us, that we might receive the adoption of sons-that we might no longer be accounted and treated as servants, but as sons grown up to maturity, who are allowed greater freedoms, and admitted to larger privileges, than while they were under tutors and governors. This the course of the apostle's argument leads us to take notice of, as one thing intended by this expression, though no doubt it may also be understood as signifying that gracious adoption which the gospel so often speaks of as the privilege of those who believe in Christ. Israel was God's son, his first-born, Rom. 9:4. But now, under the gospel, particular believers receive the adoption; and, as an earnest and evidence of it, they have together therewith the Spirit of adoption, putting them upon the duty of prayer, and enabling them in prayer to eye God as a Father (v. 6): Because you are sons, God hath sent forth the Spirit of his Son into your hearts, crying Abba, Father. And hereupon (v. 7) the apostle concludes this argument by adding, Wherefore thou art no more a servant, but a son; and, if a son, then an heir of God through Christ; that is, Now, under the gospel state, we are no longer under the servitude of the law, but, upon our believing in Christ, become the sons of God; we are thereupon accepted of him, and adopted by him; and, being the sons, we are also heirs of God, and are entitled to the heavenly inheritance (as he also reasons Rom. 8:17), and therefore it must needs be the greatest weakness and folly to turn back to the law, and to seek justification by the works of it. From what the apostle says in these verses, we may observe,

1. The wonders of divine love and mercy towards us, particularly of God the Father, in sending his Son into the world to redeem and save us,-of the Son of God, in submitting so low, and suffering so much, for us, in pursuance of that design,-and of the Holy Spirit, in condescending to dwell in the hearts of believers for such gracious purposes.

2. The great and invaluable advantages which Christians enjoy under the gospel; for, (1.) We receive the adoption of sons. Whence note, It is the great privilege which believers have through Christ that they are adopted children of the God of heaven. We who by nature are children of wrath and disobedience have become by grace children of love. (2.) We receive the Spirit of adoption. Note, [1.] All who have the privilege of adoption have the Spirit of adoption-all who are received into the number partake of the nature of the children of God; for he will have all his children to resemble him. [2.] The Spirit of adoption is always the Spirit of prayer, and it is our duty in prayer to eye God as a Father. Christ has taught us in prayer to eye God as our Father in heaven. [3.] If we are his sons, then his heirs. It is not so among men, with whom the eldest son is heir; but all God's children are heirs. Those who have the nature of sons shall have the inheritance of sons.
